This article revisits regulatory debates about environmental valuation following the Exxon Valdez oil spill to argue that the spill can be seen as a constitutive moment in the rise of neoliberalism. I show that rationalizing environmental values was not simply about applying market rationality to the natural world, but entailed reexamining the nature of that rationality itself and its relevance to social behavior. I then trace the reverberations of these debates beyond the realm of environmental policy, highlighting an underappreciated legacy of the Valdez: the first credit default swap, executed in response to an unprecedented punitive fine leveled against Exxon. Illuminating the linked histories of environmental valuation, corporate environmentalism, and financialization through that event, I argue that environmental valuation is a political problem through which neoliberal strategies for the governance of life (both human and nonhuman) have been forged. 相似文献

About 93.1 million workers were covered under workers' compensation laws in 1988--an increase of 11 percent from the 1984 total. Benefit amounts totaled $30.7 billion--an increase of about 56 percent since 1984. Of the total payments made under the workers' compensation program, $17.6 billion went to disabled workers, $1.6 billion to their survivors, and $11.5 billion for medical care. The Social Security Administration (SSA) is interested in measuring economic security in the United States, and workers' compensation plays a large role in that measurement. This article represents one part of our overall effort to determine the roles the various income-maintenance programs play in helping citizens of the United States achieve economic security. The figures presented here provide readers with an opportunity to review workers' compensation program operations during much of the 1980's. Workers' compensation is also important to SSA because that program is directly related to the Social Security Disability Insurance program. Since 1965, Social Security disability benefits have been subject to reduction if the beneficiary also receives workers' compensation and the combined benefits exceed 80 percent of previous earnings. In addition, SSA has been directly involved in providing income maintenance for disability from work-related diseases since 1969 when the Federal Black Lung benefits program was established. 相似文献

In Garcia v. San Antonio Metropolitan Transit Authority (1985),a majority of the U.S. Supreme Court's justices did violenceto the principles of the U.S. Constitution by leaving the statesto take their Tenth Amendment complaints to the Congress. Inabdicating their proper constitutional role, the majority ofjustices ignored history, political realities, and constitutionalprinciple. The Constitution's institutional arrangements, ofwhich federalism is a key component, are an intrinsic part ofthe constitutional scheme by which government power is limitedand individual rights are protected. 相似文献

The 84.3 million workers protected by workers' compensation laws in 1985 represented 87 percent of all wage and salary workers in that year. Both the amount of benefits paid to workers and the cost of the program to employers rose substantially from 1984 to 1985. Benefit payments totaled $22.5 billion-14.1 percent higher than in 1984 and the largest annual increase since 1978-79. About two-thirds of the payments in 1985 were money payments ($15.1 billion) and the remainder ($7.4 billion) went for medical care for disabled workers. Private insurance companies made nearly three-fifths of these payments and State funds and self-insured employers each paid about one-fifth of the total benefit amount in 1985. For the first time since 1978, the annual growth in employer costs exceeded the growth in workers' benefits, resulting in a slight decrease in the loss ratio for 1984-85. Employer costs were up nearly 17 percent from the previous year, reaching an estimated $29.3 billion. Covered payrolls increased by 7 percent in that same period. Total benefit payments as a percent of payroll also increased noticeably in 1985. 相似文献

In a double-blind placebo controlled study on psychomotor skills important for car driving (Study 1), a 75 mg dose of +/- 3,4-methylenedioxymethamphetamine (MDMA) was administered orally to 12 healthy volunteers who were known to be recreational MDMA-users. Toxicokinetic data were gathered by analysis of blood, urine, oral fluid and sweat wipes collected during the first 5h after administration. Resultant plasma concentrations varied from 21 to 295 ng/ml, with an average peak concentration of 178 ng/ml observed between 2 and 4h after administration. MDA concentrations never exceeded 20 ng/ml. Corresponding MDMA concentrations in oral fluid, as measured with a specific LC-MS/MS method (which required only 50 microl of oral fluid), generally exceeded those in plasma and peaked at an average concentration of 1215 ng/ml. A substantial intra- and inter-subject variability was observed with this matrix, and values ranged from 50 to 6982 ng/ml MDMA. Somewhat surprisingly, even 4-5h after ingestion, the MDMA levels in sweat only averaged 25 ng/wipe. In addition to this controlled study, data were collected from 19 MDMA-users who participated in a driving simulator study (Study 2), comparing sober non-drug conditions with MDMA-only and multiple drug use conditions. In this particular study, urine samples were used for general drug screening and oral fluid was collected as an alternative to blood sampling. Analysis of oral fluid samples by LC-MS/MS revealed an average MDMA/MDEA concentration of 1121 ng/ml in the MDMA-only condition, with large inter-subject variability. This was also the case in the multiple drug condition, where generally, significantly higher concentrations of MDMA, MDEA and/or amphetamine were detected in the oral fluid samples. Urine screening revealed the presence of combinations such as MDMA, MDEA, amph, cannabis, cocaine, LSD and psilocine in the multiple-drug condition. 相似文献
